Problem: Bambu Studio on Mac OS will not load perfectly good STL files that other slicers use
Studio Version: 1.03.00.25
Platform: MacOS 13.0.1 on MacBook Pro M1
Steps to reproduce:

  1. Open Bambu Studio
  2. Try to import any STL file
  3. Notice the info boxes. Loading of a model file has failed… File does not contain any geometry data. This is not true… Every other (Prussia, Cura, etc) will load the file with no issue.

Problem: Bambu Studio selects the wrong filament type
Studio Version: 1.03.00.25
Platform: Windows (10 Pro)
Steps to reproduce:

The bug I discovered occurs when two filaments are loaded in the printer which have been assigned the same type and color. In my case, I had loaded two white PLA filaments into AMS slots 1 and 2, but the first was glossy and the second was opaque. Using Bambu Studio I then synchronized the AMS filaments with the software and then assigned material 2 (opaque PLA) to the piece to be printed, but here the bug occurred: Bambu Studio ignored my choice and assigned the filament slot 1 (glossy PLA) to the piece to be printed …
Hope this problem can be solved soon.

Problem: Bambu Studio is printing the outer wall FASTER than inner walls despite the slicer being set up with the outer wall speed SLOWER than the inner walls. It appears that the slicer has transposed the variables.
Studio Version: 1.03.01.01
Platform: Windows 10
Steps to reproduce:

  1. Set up a model in Bambu Studio with the outer wall speed set at 200mm/s and inner walls set at 300mm/s
  2. Slice and print the model.
  3. Observe and listen for the tonal difference as the printer prints inner walls vs. the outer wall. The pitch of the outer wall laydown will be HIGHER than the inner walls. Higher pitch equals higher speed.
  4. To verify, use a stopwatch to time an inner wall laydown vs. an outer wall laydown. The outer wall will be FASTER. It should be SLOWER with the settings as described.

Other information: Windows 10 on HP Envy laptop w/ AMD 10 core processor.
X1 Carbon w/ 01.01.01.00 firmware.

This is still an issue and is really starting to get annoying. As much as I love having to get out my phone and open the ‘Handy’ app to figure out what the error code is trying to tell me on my Mac…

I’m getting the same after BambuStudio crashes my computer mid-slice

Not sure where to put this but the internal file for the dual color film sticking tool is a total mess. It has layers going over top of other layers on the same layer. Just a total mess. Destroys the nozzle and print bed. It should be removed or fixed immediately.

Problem: Pause doesn’t work in “Print sequence/By object” mode
Studio Version: 1.4.2.13
Platform: Windows 10

  1. Open Bambu Studio
  2. Slice a model with “Print sequence/By object” mode
  3. Add pause on layer 2
  4. Start print, doesn’t pause
  5. Clear build plate
  6. Slice a model with “Print sequence/By layer” mode
  7. Start print, pauses fine.






Hello I am currently running into issues that my commissioned print is failing repeatedly due to not adhering to the bed I have cleaned/flipped adjusted heat ect but it will fail 90% of the time I have including some photos that the STL will not adjust with the raft be it 1mm or 100mm it stays the same size with or without supports while the other picture shows that a different STL can adjust just fine. Is there a way to fix this STL or fix the bambu slicer that it will adjust the raft when its set to the different MM I have gone though 3/4 or a roll of filament so far just trying to test different options, I am trying not to lay it down due to keeping the surface free of rough spots and saving time with sanding and also letting me print 6 at a time vs 3… any guidance would be helpful

I am experiencing that same issue now for the first time. How do I fix it

I am experiencing the same issue. Do you know a fix

After the Update today 4/26/2023 usa Bambu Studio doesnt print when sent to print, after i slice the file and click on print plate it pops up the screen everything is normally says it sent successfully and changes to the device page but doesnt. Nothing happens I was able to find it on the printer sd card and print from there but it doesnt start the print like before. The only way i was able to print was from the sd card on the printer.

I had the exact same thing happen. Just updated the firmware and then sent a print with studio. The print did not start but was on the sd card. I like the fact that it went to the card but I wanted it to start also…

@that-jim Have you tried again recently? The status page is showing services are working again
